A skin disease and needs assessment analysis of the displaced Rohingya population in the Kutupalong refugee camp, Bangladesh.

The physical, psychological and financial burden of skin disease in low- to middle-income countries, where access to skincare is limited, is poorly understood. A group that we know very little about in this regard are refugees. There are limited data on the range of skin diseases and skincare needs of this group. To better understand the skincare needs of the displaced Rohingya population residing in the Kutupalong refugee camp, Bangladesh, we collected data on demographics, living conditions and range of dermatoses. In the 380 patients assessed, fungal skin infections, predominantly dermatophytes, were by far the most common skin disease seen (n = 215), followed by dermatitis (n = 81). Skin disease can be the presenting feature in many systemic conditions and may cause significant secondary complications itself. Developing a better understanding of the skincare needs of the refugee population is essential for future healthcare planning for this vulnerable group.

Factors associated with pruritic papular eruption of human immunodeficiency virus infection in the antiretroviral therapy era.

BACKGROUND: Pruritic papular eruption (PPE) of HIV is common in HIV-infected populations living in the tropics. Its aetiology has been attributed to insect bite reactions and it is reported to improve with antiretroviral therapy (ART). Its presence after at least 6 months of ART has been proposed as one of several markers of treatment failure. OBJECTIVES: To determine factors associated with PPE in HIV-infected persons receiving ART. METHODS: A case-control study nested within a 500-person cohort from a teaching hospital in Mbarara, Uganda. Forty-five cases and 90 controls were enrolled. Cases had received ART for ≥ 15 months and had an itchy papular rash for at least 1 month with microscopic correlation by skin biopsy. Each case was individually matched with two controls for age, sex and ART duration. RESULTS: Twenty-five of 45 cases (56%) had microscopic findings consistent with PPE. At skin examination and biopsy (study enrolment), a similar proportion of PPE cases and matched controls had plasma HIV RNA < 400 copies mL(-1) (96% vs. 85%, P = 0·31). The odds of having PPE increased fourfold with every log increase in viral load at ART initiation (P = 0·02) but not at study enrolment. CD4 counts at ART initiation and study enrolment, and CD4 gains and CD8(+) T-cell activation measured 6 and 12 months after ART commencement were not associated with PPE. Study participants who reported daily insect bites had greater odds of being cases [odds ratio (OR) 8·3, P < 0·001] or PPE cases (OR 8·6, P = 0·01). CONCLUSIONS: Pruritic papular eruption in HIV-infected persons receiving ART for ≥ 15 months was associated with greater HIV viraemia at ART commencement, independent of CD4 count. Skin biopsies are important to distinguish between PPE and other itchy papular eruptions.

Bacillary angiomatosis masquerading as Kaposi's sarcoma in East Africa.

BACKGROUND: Bacillary angiomatosis (BA) is a rare manifestation of infection caused by Bartonella species, which leads to vasoproliferative lesions of skin and other organs. Bacillary angiomatosis affects individuals with advanced HIV disease or other immunocompromised individuals. In sub-Saharan Africa, despite the high prevalence of HIV infection and documentation of the causative Bartonella species in humans, mammalian hosts, and arthropod vectors, BA has only rarely been described. METHODS: Three adult patients from Uganda and Kenya with deep purple dome-shaped papules or nodules of the skin underwent punch biopsies for histopathologic diagnosis. The biopsies of all 3 patients were sent to a local pathologist as well as to a dermatopathologist at the University of California, San Francisco. RESULTS: All 3 patients were clinically suspected to have Kaposi's sarcoma (KS), and local pathologists had interpreted the lesions as KS in 2 of the cases and nonspecific inflammation in the third. Histologic examination by dermatopathologists in the United States revealed nodular dermal proliferations of irregular capillaries lined by spindled to epithelioid endothelial cells. The surrounding stroma contained a mixed inflammatory infiltrate with lymphocytes, eosinophils, and neutrophils. Extracellular deposits of pale amphophilic granular material were noted in the surrounding stroma. A Warthin-Starry stain highlighted clumps of bacilli, confirming the diagnosis of BA. CONCLUSIONS: These 3 cases, to our knowledge, are the first reports of BA in East Africa in the biomedical literature. Each had been originally incorrectly diagnosed as KS. We speculate BA is underdiagnosed and underreported in resource-poor regions, such as sub-Saharan Africa, that have high endemic rates of HIV infection.

Cutaneous squamous cell carcinoma in human immunodeficiency virus-infected patients. A study of epidemiologic risk factors, human papillomavirus, and p53 expression.

OBJECTIVE: To examine risk factors for the development of cutaneous squamous cell carcinoma (SCC) in a group of human immunodeficiency virus (HIV)-infected patients, including evaluation and detection of epidemiologic risk factors of human papillomavirus (HPV) and p53 expression. DESIGN: Case-control study during a 3-year period. SETTING: Dermatologic referral center. PATIENTS: Thirty-three HIV-infected patients who had 97 SCCs were compared with 24 HIV-infected patients who had 70 basal cell carcinomas (BCCs). MAIN OUTCOME MEASURES: Age, skin type, amount of sun exposure, actinic damage, family history of skin cancer and history of smoking and warts. Specimens of SCC and BCC were examined for HPV using polymerase chain reaction. Presence of p53 was examined using immunohistochemical analysis. Specimens from tumor-free, non-sun-exposed areas from these same patients were used as controls. RESULTS: Risk factors for the development of both types of carcinoma included fair skin type and excessive sun exposure (> 6 h/d during the previous 10 years). The HIV-infected patients with SCCs tended to have outdoor occupations. The location of SCCs favored the head and neck; BCCs were located on the trunk. Patients with SCCs had later-stage HIV disease than did patients with BCCs. Half of the patients with SCC had a history of genital or nongenital warts. Seventy-one percent (17/24) had a smoking history. No statistical difference existed between patients with SCCs and BCCs for history of smoking or warts. Human papillomavirus was not found in most of our SCC, BCC, or control specimens. However, 92% (22/24) of the SCC specimens and 90% (18/20) of the BCC specimens stained for p53. Control specimens from non-sun-exposed skin of HIV-infected patients did not stain for p53. Epidermal staining was present in 95% (17/20) of tissue adjacent to SCCs and 47% (7/15) of tissue adjacent to BCCs. A significantly positive correlation existed between the amount of sun exposure and the amount of p53 staining seen in adjacent epidermal tissue (r = 0.07; P = .01). CONCLUSIONS: Risk factors for the development of SCCs and BCCs in HIV-infected patients are similar: fair skin type and excessive sun exposure. Our study does not support that HPV is an oncogenic factor in the development of these cutaneous tumors but provides evidence that p53 overexpression may play a role.

Photosensitivity in HIV-infected individuals.

OBJECTIVE: To characterize photosensitivity in HIV-infected individuals using minimal erythema dosage (MED) UVA (ultraviolet A light) and UVB (ultraviolet B light) photoprovocation light testing. DESIGN: Prospective, controlled analytical study. SETTING: University of California, San Francisco, between March 1995 and January 1997. PATIENTS: 13 HIV-seropositive patients with clinical and pathological features consistent with photodermatitis, 13 HIV-seropositive patients with biopsy-proven eosinophilic foliculitis (EF), and 10 HIV-seropositive patients with CD4 (T helper cell) count below 200 cells/uL and no history of photosensitivity or EF. INTERVENTION: Each patient underwent MED testing for UVB. All 13 patients with suspected photodermatitis underwent full photochallenge testing with UVA and UVB for up to 10 consecutive week days. RESULTS: Mean MED to UVB in patients with clinical photosensitivity and EF was lower (p = 0.004 and p = 0.022 respectively) than that of patients without a clinical history of photodermatitis. There were no significant differences in mean CD4 count or Fitzpatrick skin type. Positive photochallenge tests (papular changes at site of provocative light testing) to UVB (9 of 13 patients) were much more common than reactions to UVA (3 of 13 patients) in the photodermatitis group. All patients with clinically active photodermatitis developed papular changes at the site of UVB photochallenge testing, but only 1 of 5 patients with photodermatitis in remission developed papular changes with UVB photochallenge testing. Seven of the 13 patients with photodermatitis had Native American ancestry. Photosensitive patients were commonly taking trimethoprim-sulfamethoxazole (TMP-SMX), but no more commonly than EF or control patients. CONCLUSIONS: Photosensitivity in HIV-infected individuals appears to be a manifestation of advanced disease. Most patients are sensitive to UVB. The most severely affected individuals are both UVB and UVA sensitive, and may show reactions to visible light. A significant Native American ancestry may be a risk factor for development of photodermatitis in patients with advanced HIV disease. Finally, patients with eosinophilic folliculitis may be subclinically photosensitive.

Fat redistribution in HIV disease.

BACKGROUND: Abnormal distributions of body fat have been reported in association with HIV infection, including cases of both regional loss and gain of fat. OBJECTIVE: We describe the spectrum of abnormal fat distribution in HIV-positive patients. METHODS: Patients were included if they demonstrated a lack of subcutaneous fat in the cheeks in the absence of generalized wasting. Patients were examined fully and photographed, and medical records were reviewed. RESULTS: Fourteen patients were seen. Further abnormalities of body fat distribution were noted in all patients. We found a consistent pattern of fat loss in the cheeks, temples, and extremities as well as fat gain over the neck, upper back, mastoid processes, chest, and visceral abdomen. CONCLUSION: A consistent syndrome of body fat redistribution is seen in HIV-positive patients. A characteristic pattern of fat loss in the cheeks may serve as a specific marker of HIV-related fat redistribution.

The use of methotrexate for treatment of psoriasis in patients with HIV infection.

The use of methotrexate (MTX) has been contraindicated for treatment of severe psoriasis in HIV infection on the basis of six previously reported cases in which MTX appeared to potentiate opportunistic infections and accelerate HIV disease. We describe three HIV-infected patients who were given MTX for severe psoriatic arthritis. In two patients opportunistic infections did not develop. On the basis of survival data, it is not clear that use of MTX adversely affected the natural course of their HIV disease.

Psoriasis and human immunodeficiency virus infection.

BACKGROUND: Psoriasis associated with human immunodeficiency virus (HIV) infection has been reported to be severe and perhaps associated with decreased survival. OBJECTIVE: Our purpose was to document the natural history, response to therapy, and effect of psoriasis and its treatment on survival in HIV-infected patients with psoriasis. METHODS: This was an observational cohort study of 50 persons with psoriasis and HIV infection followed up during a 2-year period. RESULTS: In one third of the patients the psoriasis appeared before 1978, the year when HIV seroconversion began in San Francisco (group I). In two thirds psoriasis developed after 1978 (group II). Group I had a lower mean age of onset (19 vs 36 years) and more commonly had a family history of psoriasis. Palmoplantar and inverse psoriasis were more common in group II. Severe psoriasis occurred in one fourth of this group (12 of 50 patients). The median survival in this group after diagnosis of acquired immunodeficiency syndrome (AIDS) was 19 months, which is comparable to the median survival for all AIDS patients diagnosed in San Francisco between 1984 and 1990. CONCLUSION: Psoriasis in the setting of HIV disease may be mild, moderate, or severe. Standard therapies and zidovudine are effective in management. Survival does not seem to be adversely affected by the presence of psoriasis or its therapy.

Sarcoidosis in a patient with AIDS: a manifestation of immune restoration syndrome.

Sarcoidosis has been rarely reported in the presence of HIV infection. Helper T-lymphocyte depletion may attenuate granuloma formation. We present a patient who developed active sarcoidosis after being started on highly active antiretroviral therapy (HAART), which increased his CD4 count and decreased his viral load. There have been reports of exaggerated responses to mycobacteria and viruses with the restoration of T-cell function after HAART in HIV-infected patients. We propose that active sarcoidosis seen in this patient is also a manifestation of this newly observed "immune restoration disease."

Prevalence and predictors of skin disease in the Women's Interagency HIV Study (WIHS).

OBJECTIVE: We attempted to determine the prevalence and predictors of skin disease in a cohort of women with and at risk for HIV infection. METHODS: We analyzed baseline data from a multicenter longitudinal study of HIV infection in women. RESULTS: A total of 2018 HIV-infected women and 557 HIV-uninfected women were included in this analysis. Skin abnormalities were reported more frequently among HIV-infected than uninfected women (63% vs 44%, respectively; odds ratio [OR] 2.10; 95% confidence interval [95% CI], 1.74-2.54). Infected women were also more likely to have more than 2 skin diagnoses (OR, 3.27; 95% CI, 1.31-8.16). Folliculitis, seborrheic dermatitis, herpes zoster, and onychomycosis were more common among HIV-infected women (P < .05). Independent predictors of abnormal findings on skin examination in the infected women were African American race (OR, 1.38; 95% CI, 1.07-1.77), injection drug use (OR, 2.74; 95% CI, 2.11-3.57), CD4(+) count less than 50 (OR, 1.68; 95% CI, 1.17-2.42), and high viral loads (100,000-499,999 = OR, 1.77; 95% CI, 1.32-2.37; > 499,999 = OR, 2.15; 95% CI, 1.42-3.27). CONCLUSION: HIV infection was associated with a greater number of skin abnormalities and with specific dermatologic diagnoses. Skin abnormalities were also more common among women with CD4(+) cell depletion or higher viral load.

The National Depressive and Manic-Depressive Association consensus statement on the undertreatment of depression.

OBJECTIVE: A consensus conference on the reasons for the undertreatment of depression was organized by the National Depressive and Manic Depressive Association (NDMDA) on January 17-18, 1996. The target audience included health policymakers, clinicians, patients and their families, and the public at large. Six key questions were addressed: (1) Is depression undertreated in the community and in the clinic? (2) What is the economic cost to society of depression? (3) What have been the efforts in the past to redress undertreatment and how successful have they been? (4) What are the reasons for the gap between our knowledge of the diagnosis and treatment of depression and actual treatment received in this country? (5) What can we do to narrow this gap? (6) What can we do immediately to narrow this gap? PARTICIPANTS: Consensus panel members were drawn from psychiatry, psychology, family practice, internal medicine, managed care and public health, consumers, and the general public. The panelists listened to a set of presentations with background papers from experts on diagnosis, epidemiology, treatment, and cost of treatment. EVIDENCE: Experts summarized relevant data from the world scientific literature on the 6 questions posed for the conference. CONSENSUS PROCESS: Panel members discussed openly all material presented to them in executive session. Selected panelists prepared first drafts of the consensus statements for each question. All of these drafts were read by all panelists and were edited and reedited until consensus was achieved. CONCLUSIONS: There is overwhelming evidence that individuals with depression are being seriously undertreated. Safe, effective, and economical treatments are available. The cost to individuals and society of this undertreatment is substantial. Long suffering, suicide, occupational impairment, and impairment in interpersonal and family relationships exist. Efforts to redress this gap have included provider educational programs and public educational programs. Reasons for the continuing gap include patient, provider, and health care system factors. Patient-based reasons include failure to recognize the symptoms, underestimating the severity, limited access, reluctance to see a mental health care specialist due to stigma, noncompliance with treatment, and lack of health insurance. Provider factors include poor professional school education about depression, limited training in interpersonal skills, stigma, inadequate time to evaluate and treat depression, failure to consider psychotherapeutic approaches, and prescription of inadequate doses of antidepressant medication for inadequate durations. Mental health care systems create barriers to receiving optimal treatment. Strategies to narrow the gap include enhancing the role of patients and families as participants in care and advocates; developing performance standards for behavioral health care systems, including incentives for positive identification, assessment, and treatment of depression; enhancing educational programs for providers and the public; enhancing collaboration among provider subtypes (eg, primary care providers and mental health professionals); and conducting research on development and testing of new treatments for depression.
